Flexible Microfluidic Based Sensors

We develop a liquid-based thin film microfluidic tactile sensor with high flexibility, robustness and sensitivity. The microfluidic elastomeric structure comprises a pressure sensitive region of microfluidic channels filled with a liquid metal. Our sensor is wearable and able to differentiate and quantify pressures exerted by distinct bodily actions, such as a finger touch or footstep pressure. This liquid-based microfluidic tactile sensing platform has potential for a wide range of healthcare monitoring and robotic sensing applications.
